* @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)
* when:
* Function Type/Function: T0 is a function type and T1 is Function
* @description Check that if type T0 is a function type and T1 is Function then
* T0 is a subtype of T1. Test generic function without actual arguments but
* returning some value
* @author
* @description Check that if type T0 is a subtype of a type T1, then instance
